科技合作是“泛珠三角”区域合作的重要领域,而科技合作的开展是以科学合理的科技资源配置为基础的。科技资源的状况、科技资源效能的发挥程度不仅是“泛珠三角”区域科学技术水平的重要标志,而且是衡量其综合实力、发展后劲的重要尺度。本文分析了“泛珠三角”区域科技资源配置的现状,指出其存在的问题,并提出了优化配置本区域科技资源的建议和对策。     

长江口北支潮流沙体沉积物来源分析

通过对兴隆沙地区沉积物环境磁学特征分析，发现该地区磁性矿物主要以来源于长江亚铁磁性矿物为主，并含有少量的反铁磁性矿物；通过微体古生物特征分析，发现长江口北支沉积物主要由潮流流携带而来．综合环境磁学和微体古生物学特征，得出该地区沉积物的来源是多源的,以长江源为主．     

“Fear God; Fear the Bogaze”: The Nile Mouths and the Navigational Landscape of the Medieval Nile Delta,Egypt

By the fourth/tenth century, Egypt's Nile Delta had just two major Delta branches debouching directly into the Mediterranean – the Dumyā? (Damietta) and Rashīd (Rosetta). Navigational conditions at these branches’ mouths were treacherous because of a combination of currents, winds, wave-fields and shifting sandbanks. These conditions were a danger to shipping, and so had a formative effect on the navigational landscape of the Delta. Despite its remoteness from the Nile, Alexandria remained Egypt's chief Mediterranean port, but only because river connections were maintained that avoided the Rashīd mouth. In contrast, the port of Rashīd was relatively insignificant. Similar conditions at the Dumyā? mouth prompted navigators to adopt routes via Lake Tinnīs, modern Lake Manzala, which linked to the sea through its calmer sea mouths. This article brings together material from multiple disciplines to offer a new understanding of the navigational context of Egypt's medieval Mediterranean ports.

Sleep quality in athletes under normobaric hypoxia equivalent to 1500 m altitude: A polysomnographic study

Abstract

In the present study, we evaluated the duration of slow-wave sleep (Stage 3 and 4) and total delta power (< 3Hz) in all-night non-rapid eye movement (NREM) sleep electroencephalograms (EEGs) of athletes during normobaric hypoxia at simulated altitudes of 1500 m. Seven male athletes slept for two nights in a normoxic condition and one night in an hypoxic condition equivalent to an altitude of 1500 m. Whole-night polysomnographic recordings, thoracic and abdominal motion, nasal and oral airflow, and blood oxygen saturation (SpO₂) were recorded. Visual sleep stage scoring and fast Fourier transformation analyses of EEG were performed using 30-s epochs. Mean and minimum SpO₂ decreased significantly during sleep in the hypoxic condition. Between groups, changes in heart rate, respiratory disturbance measures including apnoea and hypopnoea, slow-wave sleep and total delta power of the all-night NREM sleep EEG were small and non-significant for the hypoxic condition_. However, individual difference in time at an SpO₂ below 90% were large in the hypoxic condition, and both slow-wave sleep and total delta power of all-night NREM sleep EEG decreased in three participants who spent a prolonged time below 90% SpO₂. The present results suggest that monitoring time below 90% SpO₂ is recommended when studying individuals' living-high schedule even under hypoxic conditions equivalent to an altitude of 1500 m.     

"十一五"期间长江三角洲学校体育场地设施发展战略研究

运用文献资料、专家访谈、问卷调查、数理统计等方法对长江三角洲中的学校体育场地器材设施进行了分析研究,认为:目前长江三角洲大多数学校体育场地设施没有达到长江三角洲的学校体育场地器材的配置标准,现有场地也做不到全部开放,学生对学校内体育场地设施的满意程度较低.提出了长江三角洲学校体育场地设施"十一五"发展战略,并建议由各个地区政府出面来规划、运作学校体育场馆设施,坚持以学校为中心规划、配置体育场地设施,设立学校体育场地设施建设专用经费,以法律的形式出台学校体育场地的法规等,以促进长江三角洲学校体育场地"十一五"发展战略的实施.
